SPECIFICATION forming part of Letters Patent No. 714,203, dated November 25, 1902.

Application filed March 31.1902- Serial No. 100.858. (No model.) i

To all whmn zltmay concern:

Be it known that we, THOMAS J. LEVY and MONT ANDERSON, citizens of the United States, residing at Liberty, in the county of Maricopa and Territory of Arizona, have invented a new and useful Grain-Elevator, of which the following is a specification.

Our invention is an improved elevating apparatus adapted for elevating grain and other material; and it consists in the peculiar construction and combination of devices hereinafter fully described and claimed;

In the accompanying drawings, Figure 1 is an elevation, partly in section, of an elevating apparatus embodying our improvements. Fig. 2 is an elevation of the same at right angles to Fig. 1.

In the embodiment of our invention We construct a suitable frame 1, which is here shown as comprising vertical corner-posts 2,a ground or base frame 3, plates 4, cross-bars 5, which connect the posts together on opposite sides of the frame, cross-bars 6, which are disposed at right angles to the cross-bars 5 and above the same, and cross-bars 7 which are carried by cross-bars 6. A shaft 8 has its bearings 9 secured on the ground-frame and a shaft 10 has its bearings 11 secured on the bars 7. The shafts 8 10 are respectively provided with sprocket-wheels 12 13, there being two of said sprocket-wheels on each of said shafts and spaced a suitable distance apart. A flexible endless carrier 14 is supported and operated by the sprocket-wheels 12 13. The said flexible endless carrier comprises a pair of sprocket-chains 15, each of which is endless and engages a pair of the sprocket-wheels 12 13, and buckets 16, which are disposed transversely between, connect and are carried by said endless sprocket-chains. The said buckets are provided at their ends with projecting trunnions 17, which extend beyond the outer sides of the endless chains 15 and are provided with tappets, which are here shown as antifriction-rollers 18, that revolve on the said trunnions. The lower portion of the carrier operates in the material, whether grain or other material to be elevated, and we have here shown a boot 19 thus disposed with relation to the endless carrier and to which when the invention is to be used for elevating grain the grain to be elevated is conveyed by chutes or otherwise from the. bin, car, or other vessel or structure in which the grain is stored. We will have it understood, however,tl1at we do not limit ourselves to the ployment of the boot in connection with our elevating apparatus, as within the scope of our invention the same may be dispensed with.

A pair of vertical shafts 20 are mounted in bearings 21 22, which are respectively disposed on the cross-bars 5 and the plates 4. The said shaftsare on opposite sides of the flexible endless carrier and in line with one lead thereof, as shown in Fig. 2. Each of said shafts is provided with a spiral cam 23, said cams being revoluble with said shafts and adapted to engage the under sides of the tappets 18 in succession on one lead of the endless traveling carrier, so that when the said shafts are rotated in the appropriate direction said cams by thus engaging said tappets communicate power and motion to the flexible endless carrier, so that the same will move, as indicated by the arrows in Fig. 1. Hence the respective buckets of the flexible endless carrier-will successively become filled with grain or other material as they pass under the sprocket-wheels 12 and will be overturned and discharged of their contents as they pass over the elevated wheels 13. A suitable chute or trough (not shown) will in practice be employed to catch the grain or other material discharged from the buckets as they pass Over the wheels 13. 7

Each of the shafts 20 has a spur-pinion 24 fixed to its upper end. A horizontally-disposed spur-wheel 25, which is the masterwheel and which engages with the spur-pinion 24, is disposed on the upper side of the frame 1 and suitably mounted for revolution, the bearing for said wheel being indicated at 26. A sweep-lever 27 is here shown as attached to the said master-wheel, by means of which the latter may be rotated to impart rotary motion to the pinion 24, and hence to the spiral cams 23, to operate the flexible endless carrier, as hereinbefore described.

Having thus described our invention, we claim- 1. The combination of revoluble supporting elements, a flexible endless-carrier element carried thereby and having buckets and tappets on one lead of each of said chains, pinions on said shafts, a master-wheel engaging said pinions and a sweep-lever to rotate said master-wheel, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two Witnesses.
